I'm all for the “innerverse”. However, the danger of juxtaposing the “innerverse” with the metaverse (and naming it so) is that people will approach it the wrong way and expect that always "consistent reliable repeatable" experience.
The mindset is very different. It is more about a subtle/introspective/meditative/mindfull inner-discovery than an "automatic" (consistent reliable repeatable) entertainment.
I'm not saying you are doing it this way. I'm just wary of people eventually coming to it from the neuralink angle and trying to quantify and control it to death (quite literally, because dreams are fragile things)
